Essays on the Effectiveness of Conditional Free Shipping Policies on Customers’ Purchase Behaviors and Retailers’ Profitability
(2022-04-06)
With the proliferation of e-commerce, designing a free shipping policy that can balance the need to recover shipping costs and retain customers is a big quandary for retailers. This dissertation investigates the effectiveness ...
Pipeline Collision Avoidance for Excavation Work Using Magnetic Anomaly Detection (MAD)
(2022-04-11)
Uncertainty of the precise location of underground pipelines poses a safety risk to excavator operators and nearby construction workers. Excavator collisions with pipeline carrying hazardous material can result in significant ...
Closed-Loop Non-Invasive Brain Stimulation as a Fatigue Countermeasure
(2022-03-24)
Cognitive fatigue is a pressing issue across multiple job domains, especially within safety critical systems, where fatigue-driven lapses in operator performance and behavior have resulted in costly errors. While the ...
Essays on the Determinants of Health and Labor Market Outcomes
(2022-04-20)
There is increasing evidence that an individual’s experiences, setting, and resource access during early childhood and education years have a profound impact on productivity, income, and health in adulthood. Understanding ...
An Efficient Control Framework for Robot Manipulators Performing Tasks Requiring Simultaneous Control of Tool Path and Orientation
(2022-04-18)
In this dissertation, we develop a novel planning and pose control framework for articulated
robots for motion along a spatial curve with constant speed. First, given a list of waypoints, we
develop the spatial curve along ...
The Mass Politics of Financial Markets
(2022-04-27)
Research on the role of the democratic process—and particularly that of mass political opinion—in financial markets is scarce. Extant published research that either principally or tangentially ad-dresses this subject matter ...

(2022-04-19)
Over the last two decades, a family of ternary carbides and nitrides commonly referred to as MAX phases has gathered tremendous attention of scientists and engineers. Thanks to their layered crystal structure consisting ...
The Use of Tetrazine-Norbornene Click Products in Supramolecular Hydrogel Crosslinking and the Design of Dynamic Hydrogels
(2022-01-12)
Herein, the discovery and application of a novel class of supramolecular secondary interactions between the cycloaddition products of the inverse electron-demand Diels Alder (IEDDA) tetrazine-norbornene click reaction is ...
A Flash-based Current-steering Digital to Analog Converter
(2022-04-19)
We present a novel current-steering digital to analog converter (DAC) which utilizes flash transistors as programmable, tunable current sources. Our design achieves extremely low latency, area, and power, making it especially ...
Stability of Sumac (Rhus coriaria) Polyphenolic Extract during Simulated Gastrointestinal Digestion and Colonic Fermentation
(2022-04-11)
The effects of Sumac (Rhus coriaria) polyphenolic extract were evaluated against common pathogenic and probiotic bacteria. The bacteria were individually treated with free sumac (free Su) and encapsulated sumac (NPSu) ...
